C/2014 N3 NEOWISE
more info
Comet C/2014 N3 was discovered on 4 July 2014 with Near-Earth Object Wide-field Infrared Survey Explorer, that is more than 8 months before its perihelion passage. This comet was observed until 6 January 2017.
Comet had its closest approach to the Earth on 9 October 2014 (3.30 au), five months before perihelion passage.
Solutions given here are based on data spanning over 2.51 yr in a range of heliocentric distances: 4.45 au – 3.882 au (perihelion) – 6.70 au.
This Oort spike comet suffers moderate planetary perturbations during its passage through the planetary system; these perturbations lead to a more tight future orbit (see future barycentric orbits).
